Outline of Final Research Achievements

A method to design the virtual inertia control considering the constraint of the energy storage has been developed for stabilizing the low inertia power system. This study has investigated some approaches: the output control by switching the algorithm based on frequency deviations after the disturbance, the coordinated control with synchronous generators by monitoring the state of charge of the energy storage, the control parameter design based on the sensitivity analysis, the controller design by applying the robust control, the application of the fractional order controller, and the optimization of the control parameters. The effectiveness of these approaches has been demonstrated by the numerical simulations.
